Scuba Fitness Tastic

An article in the grauniad compares Scuba Diving with Open Water Swimming for fitness benefits [guardian.co.uk]. If you weigh 70kg a 45 minute dive burns 545 calories. That's pretty damn good - and explains why I actually lost weight in the Maldives despite stuffing my face with 3 x 3 course meals a day (none of which were small). But 2 x 60 minute dives on a chunk of the days would have burned up the excess calories no probs I guess!
